This invention relates todies for shaping metalor other materials, and more, partlcularly to dies of thi kind which, are ei'nployed in the manufacture o-fcastings, and which are used for shaping or reforming distorted castings o'r difierent kinds.

7 Generally stated, the object otithe inVntion is to provide a novel and Improved con struction and arrangement, whereby sulficient pressure, and' pressure in the requisitediree,

1 tion, is brought'to 'bear .to shape or, reform a in one or more directions,

distorted casting, or for similarpurpo'ses, merely by the movement of. o11e]die toward the other, in a straight line, notwithstanding that some of thepressure necessary for correctly forming the casting, or for similar purposes, must be exerted in a direction, or at an angle to the said straight-line motion of one die toward the other, and notwithstanding that the form of the castingtis such that ordinary, dies could not be'used to straighten or reshape the casting, as will hereinafter more fully appear. o r I It is'also, an object .toziorovide certain details and features-offconstruction, and combinations tending to. increase the general eliiciency and the desirability of a casting straightening or reshaping die mechanism, or mechanism for some similar purpose, of

this particular character.

To these and other useful ends, the inventio'n consists in the matters" hereinafter set forth andclaimed, and shown in the accompanying drawings, 1n1wh1ch,.

Only aportr n of the.web'15 cou1d be: compressed directly between, the .dies. 1 and 11, because of the overhanging character of the web 16, and hence the entirelength of a the .web 15 is desirably compressed bew e the ck 6 11M11 di 1:1 in the 1m,- l hIOWI l lu dd O hfli .Qdibbldk .5 s he d birt s shame-=19,shar ware we 16'is compressed in desired manner between, theupper end pfi v block e and; the shoulderl? of.tl1e, uppr ielninthe inanner shown.v It will i in additioneto the ,straigh 1 st t e-su nam 1- -5 h tes in here e in erme iat 91. linfes or forces e gles to the ii 11 w n the di b d g ofa l t fit-l e neif ql sfa afie f ng which need, or may. need, straigh ningor that casting. Thislolock 6 has thecasting-engag- 1 reforming before the casting is suitable for use. The block (3 does not move as a part of either the upper or the lower die, of course, and hence lines of force are set up which are diflerent from what would be the case it all of the casting-engaging portions were rigid with either the upper or the lower die. The block (3 is free to move relatively to the die 1, and is free to more relatively to the die 11, andthus all parts o t' the casting which require straightening or reforming are subjected to the cleaned and necessaryprasure, in a manner that would not be possible with casting-engaging portions which were rigid with either one die or the other, and it obvious, of course, that: this same schei'ne may be employed in connection with castings of ditierent kinds, whereby thedies and the intermediate die block may be of any suitable or desired number, and of any suitable or desired tormation, depending upon the shape and. term of the casting or otherarticle to be compressed or treated.

Thus it will be seen that the casting or otherarticle is straightened or reshaped, or given the shape that it should have in one operation. In other words, it is not necessary to Subject the casting to one bending operation, and then take it out and turn it ore and reinsert itinthe same mechanism, or in a dif terent mechanism, for another shaping operation. The die blocks 1 and 11 could not be formed to engage the under surface of the web 16, 0' at least it would be ditlicult to do this, and hence with only the blocks 1 and 11, formed as nearly as possible to engage all of the webs of the (ca. ting, the web 16 would not be properly compressed, but, with the upper diezl formed to not ongage the upper surface of the web if; and with the die Il'tt'ouned tonot c1 go the under surface oi the. web to. leaving these snrfin s uncngaged by said die blocks, the interposition of the block (3 becomes possi ble and eliective to engage the surfaces of the webs 15 and 1c, in the manner shown, and thus the block. (3 is ai'lapted to co-operatie with the larger die hhjicks l and it to prop" eriy shape the casting or other article b v one bending or shaping operation, instead ol" by successive operations.

ti t course, during the bending. the sur-- face t) of the floating block (l slides on the surface it), and the surface 5 slides on the upper surface oi" said hloch, whereby the latter has sliding contact with both the upper and lower blocks or heads l. and 11, in the manner shown and described. The casting when disposed at an i angle, as shown, is in such position that the surface of the portion 16 faces downward and overhangs the upwardly facing surface of the portion 15, so that these two surfaces are at an angle to each other and could nothe engaged by anything rigid with the upper and lower heads 1 and 11 of the machine. But the block 6 tan engage the downwardly facing surface of the portion 16, and can engage the upwardly facing surface of the portion 15, as

. shown, and thus sutlicient pressure is exerted everywhere to produce the desired effect on thecasting, by simply one operation at the machine.

ll ithont disclaiming anything, and with-- out prejudice to any novelty disclosed, what 1 claim as my invention is:

t. In mechanism for shaping castings or articles, the i'-on1bim|tion of die blocks rela tirel v nu able toward and away from each other, relatively forn'ied to engage and exert pressure on the article, to shape the article, and loose or floating intermediate means unconnected to said mechanism and freely inangle to each other to engage certain portions ot the surface oil said casting or article which are disposed at: different angles and which are impossible or difiicnlt of engage ment by said blocks, said floating intermediate means co-operating with said blocks to exert; pressure on the casting or other article to straighten or shape the same in one oper ation, so that said mechanism is operative by one operation to do the required work on.

said casting or other article.

2. A. structure as specified in claim it, said loose or floating intermediate moans comprising a tree block displaceable laterally and adapted for engaging portions of the casting or other article, shaped toengage one surface of each of said die blocks, one said direction being longitudinal of said block. the other said direction being trans verse of said block. said loose l)l()Ul\ being movable relativcv-ly to both of said other bloclcs, to permit la-ndhu of portions of the casting or other article.

t. v tructure as specified in claim I, said die blocks both having shaping surfaces all disposed at oblique angles to the right-line relative inovenumt between the two l)l()t'ht and said intermediate means comprising a rectangular t'ree block dis 'ilaceablc laterally and having two surfaces for engaging the casting or other articlegand having two other surfaces for engagement with said surfaces of the two die blocks, all of the operative surfaces of said block oblique to said righthne movement.
